MOBILE APP PENETRATION TESTING
Mobile app penetration testing for Android and iOS
We test your app, the device it runs on and the APIs behind it, so customer data stays safe even on a rooted phone.
What is mobile application penetration testing?
Mobile application penetration testing checks Android and iOS apps, and the APIs they talk to, for security flaws such as insecure data storage, weak authentication, reverse engineering and certificate-pinning bypass. Testers use static and dynamic analysis aligned to the OWASP MASVS standard and MASTG testing guide.
Your app ships your code to every attacker's phone.
Once your app is on the Play Store or App Store, anyone can download it, decompile it and poke at its APIs. We test it the same way, so secrets, tokens and customer data are not sitting one reverse-engineering step away.

What we test in your app
Data storage
Tokens, PII and keys in local storage, logs and backups.
Network communication
TLS, certificate pinning and traffic interception.
Authentication & sessions
Login, biometrics, OTP and session handling.
Reverse engineering & tampering
Obfuscation, root/jailbreak detection and code tampering.
Platform interaction
Deep links, intents, WebViews and permissions.
Backend APIs
Authorisation, rate limiting and data exposure.
How we test mobile apps
Intake
APK/IPA, test accounts and scope.
Static analysis
Decompile and review code, config and secrets.
Dynamic analysis
Run on rooted/jailbroken devices, hook and intercept.
API testing
Attack the endpoints the app calls.
Reporting
MASVS-mapped findings with fixes.
Re-test
Verify fixes on the new build.
